Mortality Risk After Cardiac Surgery: Application of Inscor in a University Hospital in Brazil's Northeast.

Objective: To apply the InsCor in patients undergoing cardiac surgery in a university hospital in Brazil's northeast.

Methods: It is a retrospective, quantitative and analytical study, carried out at the University Hospital of the Federal University of Maranhão. InsCor is a remodeling of two risk score models.

Effects of Resistance Exercise Applied Early After Coronary Artery Bypass Grafting: a Randomized Controlled Trial.

Objective: To evaluate the effects of resistance exercise applied early after coronary artery bypass grafting.

Methods: It is a randomized controlled trial with 34 patients undergoing coronary artery bypass grafting between August 2013 and May 2014. Patients were randomized into two groups by simple draw: a control group (n=17), who received conventional physical therapy and an intervention group (n=17), who received, additionally, resistance exercise.

Application of Mechanical Ventilation Weaning Predictors After Elective Cardiac Surgery.

Objective: To test several weaning predictors as determinants of successful extubation after elective cardiac surgery.

Methods: The study was conducted at a tertiary hospital with 100 adult patients undergoing elective cardiac surgery from September to December 2014. We recorded demographic, clinical and surgical data, plus the following predictive indexes: static compliance (Cstat), tidal volume (Vt), respiratory rate (f), f/ Vt ratio, arterial partial oxygen pressure to fraction of inspired oxygen ratio (PaO2/FiO2), and the integrative weaning index (IWI).
